Question

they often watch tv什么evening

看例句填空 1.They often watch TV in the evening._ _they often_in the evening.
是疑问句 但they前是两个空What do they often do in the evening?这样对吗 为什么有两个do

Answer 1

1.They often watch TV in the evening.
1.他们晚上经常看电视.
改成疑问句:
What do they often do in the evening?
他们晚上经常干什么?
第一个do是助动词,用来提问的.
第二个do是实义动词,有实际意义的,是"做"的意思.
